SUMMARY OF HYDROMETRIC DATA IN 
WASHINGTON, 1878-1919. 


By Glenn L. Parker and Lasley Lee. 


INTRODUCTION. 

The United States Geological Survey began to collect records of 
stream flow in the State of Washington in August, 1893, when gaging 
stations were established on Yakima and Naches rivers. The work 
has been continued and enlarged gradually until by September 30, 
1919, a total of 1,120 years of record had been made available at 
209 gaging stations. Analyses of early records, preserved by interested 
persons, have made it possible to determine the daily discharge of 
lower Columbia River since March, 1878, and of Spokane River 
since April, 1891. 

The purpose of this report is to present, for ready reference, a 
summary of the hydrometric data obtained in the State, the details 
of which are contained in 45 different volumes published by the 
United States Geological Survey. The monthly and yearly discharge 
given herein will serve most of the needs for stream-flow data, and 
the bibliography (pp. 8-25) will facilitate reference to more detailed 
information. 

As gaging-station records are published annually, it frequently 
occurs that field work or office analysis completed after a publication 
has been issued warrants revision of original computations. These 
revisions, which of necessity appear in later publications, are often 
overlooked, and the less accurate original computations are used 
instead. The records given herein include all revised computations 
and may be considered the latest and best information available 
at this time. It should be pointed out, however, that subsequently 
additional data and more comprehensive analyses may throw new 
light on these revised computations. 

COOPERATION. 

Since 1909 successive Washington State legislatures have appro¬ 
priated funds for the use of the State Board of Geological Survey in 
cooperating with the United States Geological Survey in topographic

HYDROMETRIC DATA IN WASHINGTON, 1878-1919. 


mapping and investigations of water resources. Cooperative agree¬ 
ments have been drawn providing that, after plans acceptable to 
each organization have been formulated, the work shall be directed 
by the United States Geological Survey and paid for by equal allot¬ 
ments of State and Federal funds. 

This report has been prepared at the request of Henry Landes, 
State geologist, with the approval of the State Board of Geological 
Survey, which consists of Gov. Louis F. Hart, chairman; State 
Treasurer W. W. Sherman, secretary; Dr. Henry Suzzallo, president 
of the University of Washington; and Dr. Ernest O. Holland, 
president of the State College. 

ACKNOWLED GMENTS. 

This summary has been prepared by the water-resources branch of 
the United States Geological Survey in connection with its principal 
function of determining the daily discharge of important streams. 

Special acknowledgment is due to Mr. Henry Landes, State geolo¬ 
gist, for helpful suggestions and for the efficient manner in which he 
represented the Washington State Board of Geological Survey in 
cooperative relations. 

The writers are indebted to Mr. J. T. Hartson, Mr. L. D. Carson, 
and Miss Claudia L. Underwood for assistance in assembling and 
checking the records here given. 

DEFINITION OF TERMS. 

The volume of water flowing in a stream—the “discharge” or 
“run-off”—is expressed in various terms, each of which has become 
associated with a certain class of work. These terms may be divided 
into two groups—(1) those that represent a rate of flow, as second- 
feet, gallons per minute, and discharge in second-feet per square mile, 
and (2) those that represent the actual quantity of water, as run-off 
in inches, acre-feet, and millions of cubic feet. The principal terms 
used in this report are second-feet, second-feet per square mile, run¬ 
off in inches, and acre-feet. They may be defined as follows: 

“Second-feet” is an abbreviation for “cubic feet per second.” A 
second-foot is the rate of discharge of water flowing in a channel 1 foot 
wide and 1 foot deep at an average velocity of 1 foot per second. It 
is generally used as a fundamental unit from which others are com¬ 
puted by the use of the factors given in the tables on pages 3-6. 

“Second-feet per square mile” is the average number of cubic feet 
of water flowing per second from each square mile of area drained, on 
the assumption that the run-off is distributed uniformly as regards 
both time and area. 

“Run-off in inches” is the depth to which an area would be cov¬ 
ered if all the water flowing from it in the period stated were uni- 


CONVENIENT EQUIVALENTS.

formly distributed on the surface. It is used for comparing run-off 
with rainfall, which is usually expressed in inches. 

An "acre-foot” is the quantity required to cover an acre to the 
depth of 1 foot. 

CONVENIENT EQUIVALENTS. 

1 United States gallon of water weighs 8.34 pounds avoirdupois. 

1 cubic foot of water weighs 62.5 pounds avoirdupois. 

1 second-foot=7.48 United States gallons per second=448.8 United States gallons 
per minute=26,929.9 United States gallons per hour=646,317 United States gallons 
per day. 

1 second-foot=60 cubic feet per minute=3,600 cubic feet per hour=86,400 cubic 
feet per day=31,536,000 cubic feet per year=0.000214 cubic miles per year. 

1 second-foot=0.9917 acre-inch per hour=1.983471 acre-feet per day=723.966942 
acre-feet per year (=725.950413 acre-feOt per year of 366 days). 

1 second-foot=0.028317 cubic meter per second=1.699 cubic meters per minute= 
101.941 cubic meters per hour=2,446.58 cubic meters per day. 

1 second-foot for 1 year (365 days^) will cover 1 square mile 1.1312 feet or 13.5744 
inches deep. 

1 inch deep on 1 square mile=2,323,200 cubic feet=0.0737 second-foot for 1 year. 

1,000,000,000 (1 United States billion) cubic feet=ll,570 second-feet for one day= 
413 second-feet for one 28-day month=399 second-feet for one 29-day month=386 
second-feet for one 30-day month=373 second-feet for one 31-day month. 

100 United States gallons per minute=0.223 second-foot=0.442 acre-foot in one day. 

1 foot deep (head of 1 foot)=0.434 pound pressure on 1 square inch. 

1 cubic meter per minute=0.5886 second-foot=4.403 United States gallons per 
8econd=1.1674 acre-feet per day. 

1 cubic meter, stere, or kiloliter=1,000,000 cubic centimeters=1,000 liters=61,023.4 
cubic inches=264.17 United States gallons=35.3145 cubic feet=l.30794 cubic yards 
=0.000810708 acre-foot. 

1 acre-foot=325,851 United States gallons=43,560 cubic feet=l,613$ cubic yards= 
1,233.49 cubic meters. 

1 million gallons per day=1.55 second-feet=3.07 acre-feet per dav=2.629 cubic 
meters per minute. 

1 second-foot falling 8.81 feet=l horsepower. 

1 second-foot falling 10 feet=1.135 horsepower. 

1 second-foot falling 11 feet=l horsepower, 80 per cent efficiency. 

1 horsepower=5,694,120 foot-gallons per day=550 foot-pounds per second=33,000 
foot-pounds per minute=1,980,000 foot-pounds per hour=2,545 British thermal units 
per hour=76 kilogrammeters per second=1.27 kilogrammeters per minute=746 watts. 

1 horsepower, boiler rating, requires the evaporation of 34$ pounds per hour of 
water at 212° F. to dry steam at the same temperature; or the expenditure of 33,317 
British thermal units; and in practice is developed by burning 3$ to 4f pounds per 
hour of coal under 10 to 12 square feet of heating surface. 

1 British thermal unit=778 foot-pounds. 

1 pound of bituminous coal contains about 14,100 British thermal units, or 11,000,000 
foot-pounds of energy. 

Best steam engine efficiency is about 18 per cent and requires 1 pound of coal per 
hour per horsepower. Average efficiency is about 10 per cent and requires 1.8 pounds 
of coal per hour per horsepower. 


4 HYDROMETRIC DATA IN WASHINGTON, 1878-1919. 

CONVERSION TABLES. 

Conversion from one unit to another is a simple arithmetical 
process. The following tables afford a ready means of conversion 
between terms commonly used in hydraulic computations. Figures 
may be chosen from the tables for units, tens, hundreds, etc., and 
then combined to get the desired results. The base data will seldom 
justify use of more than three significant figures, although some 
tables give more.

EXPLANATION OF DATA. 

The data presented in this report are assembled for climatic years 
ending September 30. At the end of a calendar year much of the 
precipitation that fell during the three months preceding is stored in 
the form of snow or ice or in ponds, lakes, swamps, amd underground 
passageways. A large percentage of this stored water does not reach 
the streams until the spring and summer of the next calendar year. 
At the end of September, however, only a small amount of ground 
water remains as a part of previous precipitation, so that run-off 
for the year ending September 30 is practically all derived from pre¬ 
cipitation within that year. 

The base data collected at gaging stations consist, primarily, of 
records of stage and measurements of discharge. Records of stage 
are obtained either from direct readings on staff or chain gages or 
from water-stage recorders. A total of 51 water-stage recorders were 
in operation in the State of Washington in 1919. Measurements of 
discharge are made with a current meter according to methods 1 per¬ 
fected by the United States Geological Survey through many years 
of experience. About 650 measurements a year are required for de¬ 
termining the relation between stage and discharge at an average of 
about 90 gaging stations in Washington. 

Rating tables for each gaging station, indicating the discharge at 
any stage, are obtained by analyzing graphically the results of dis¬ 
charge measurements. Daily discharge, from which the maximum, 
minimum, monthly mean, and yearly mean discharges are computed, 
is determined by applying mean gage heights for days or for shorter 
periods to the rating tables. If streams are subject to rapid diurnal 
fluctuation the mean daily discharge is obtained (since 1915) by the 
use of a discharge integrator, an instrument operating on the principle 


1 Hoyt, J. C., and Grover, N. C., River discharge, 4th ed., pp. 61-76, New York, John Wiley & Sons. 





























ACCURACY OF DATA.

of a planimeter but controlled by mechanism introducing functions 
of the rating table in such manner that tracing a time-stage graph 
with a pointer yields reading representing discharge. 

In the monthly-discharge tables the column heading “Maximum’* 
gives the highest mean discharge for a single day during the month or 
year specified. As the crest discharge of a flood covers a period much 
less than a day the crest or extreme maximum discharge is always 
somewhat higher than the maximum given in the tables. Likewise 
the column headed “Minimum’’ represents the lowest mean discharge 
for a single day. For most of the gaging stations the extreme maxi¬ 
mum and minimum discharges are given in notes following the table 
for the last year of record. The column headed "Mean” gives the 
average flow for each second during the month. This average flow 
forms the basis of computing results shown in the remaining columns, 
except in the column headed “Accuracy.” 

Annual summary tables follow the tables of monthly discharge that 
cover five or more climatic years. 

ACCURACY OF DATA. 

The accuracy of stream-flow data depends, primarily, upon the 
permanence of relation between stage and discharge and upon the 
accuracy of observations of stage, measurements of flow, and inter¬ 
pretation of records. 

The probable accuracy of monthly mean discharge (not the maxi¬ 
mum or minimum or the mean for individual days), as judged by 
the writers or by the engineers who analyzed the base data, is shown 
by letters in the column headed “Accuracy.” The judgment was 
made after giving consideration to the permanence of relation 
between stage and discharge, the precision with which the discharge 
rating curve is defined, the refinement and reliability of gage read¬ 
ings, the frequency of gage readings, and the methods of applying 
daily gage heights to the rating table to obtain the daily discharge. 
The letter A indicates that the mean monthly flow is judged accurate 
within 5 per cent; B, within 10 per cent; C, within 15 per cent; and 
D, within 25 per cent. Unusual features relating to accuracy are 
described in footnotes. 

The monthly means for any gaging station may represent the 
actual flow passing the gage with acceptable accuracy, but the 
discharge per square mile and run-off in inches may be subject to 
considerable error on account of artificial regulation and diversion 
of water above the gage for irrigation or for other use. The “dis¬ 
charge in second-feet per square mile” and “run-off in inches” are 
therefore not computed if such errors appear probable. They are 
omitted also for any gaging station at which the average annual 


8 


HYDROMETRIC DATA IN WASHINGTON, 1878-1919. 


run-off is less than 10 inches. Corrections are made for storage, 
diversion, and depletion if sufficient information is available to com¬ 
pute the probable natural flow. The flow at some gaging stations 
is controlled sufficiently by regulation in reservoirs to produce rather 
marked changes in natural monthly flow but no material change in 
natural yearly flow, so that for these stations '‘discharge in second- 
feet per square mile” and “run-off in inches” are omitted for months 
but are computed for full years. 

All figures representing “discharge in second-feet per square 
mile” and “run-off in inches” previously published by the United 
States Geological Survey should be used with caution because of 
possible inherent sources of error not known to the Survey. 

BIBLIOGRAPHY. 


The large number of volumes containing hydrometric data for 
gaging stations in the State and the accumulation of revised figures 
of discharge superseding records published in earlier publications 
have made it seem advisable to include a bibliography in which 
gaging stations are grouped alphabetically and references given for 
each year of record. If a need arises for more information than is 
given in this report, detailed results may be found readily by con¬ 
sulting the publications cited on the following pages. 

Records were published for calendar years to 1910 inclusive and 
for climatic years ending September 30 thereafter. The numbers in 
the columns headed “Year” refer to calendar years and climatic 
years correspondingly. The records from October to December, 
1910, were duplicated when the change was made.

PUYALLUP RIVER BASIN 


45 


PUYALLUP RIVER AT PUYALLUP (18). 

Water-stage recorder (PI. II. B ) a quarter of a mile above Puget Sound Electric 
Railway bridge, 1 mile north of Puyallup, and 2 miles below Stuck River, in Pierce 
County. 

Two hydroelectric plants, owned by the Puget Sound Power & Light Co., divert 
water above the station. Water for the Electron plant is diverted from Puyallup 
River 10 miles above Electron into an equalizing basin having a capacity of 185 acre- 
feet; water used at this plant is returned directly to the river. Water for the Dieringer 
plant is diverted from White River at Buckley into Lake Tapps (capacity, 51,000 
acre-feet), and after use is discharged into Stuck River. 

Drainage area, 914 square miles; includes White River (west side) drainage area; 
measured on Plates IV and XI, Water-Supply Paper 313.

WHITE RIVER AT BUCKLEY (20). 

Gage at Northern Pacific Railway bridge 1 mile northeast of Buckley, in Pierce 
County, except from June 8 to September 30, 1910, when it was at Mud Mountain, 
5 miles upstream. 

Wire or staff gages used prior to January 18, 1913; water-stage recorder used after 
that date. 

White River flume diverts water from river half a mile above gage. Total monthly 
discharge, after flume was built, computed from determinations of combined flow of 
river and flume. 

Drainage area, 424 square miles; measured on Plate XI, Water-Supply Paper 313.

Note. —Water was shut off at Cedar Lake from Nov. 4 to 26, 1895, while a temporary dam was being 
built. The observed discharge for this period, as given in table, was less than the natural. The effect of 
storage accumulation on the monthly mean, as estimated at that time, was 246 second-feet, which would 
seem to indicate that the natural monthly mean for November, 1895, was 387 second-feet. 

Mean discharge for Dec. 13-29, 1895, takeD as mean for month; maximum and minimum discharge as 
shown in table were for that period. Monthly discharge October, 1898, to March, 1901, estimated by com¬ 
parison with record of White River at Buckley as described and given in Water-Supply Paper 313, pp. 107- 
108. Flow partly controlled by regulation in Cedar Lake reservoir after Seattle municipal plant was placed 
In operation, in January, 1905.

by months, during several years record. Mean discharge November, 1909, estimated by comparison of 
record of total flow of Snoqualmie River with records of Yakima River at Cle Elum and Cedar River near 
Ravensdale and ratio of North Fork to sum of discharge at the three forks. Monthly mean discharge 
December, 1912, January and March, 1913, estimated by comparison with records of the Middle and South 
forks and by comparison of record of total flow of Snoqualmie River with record of flow of Yakima River 
at Cle Elum. Monthly mean discharge April and May, 1913, estimated by comparison with record of 
North Fork of Skykomish River at Index.

SPOKANE RIVER BELOW LITTLE FALLS, NEAR LONG LAKE (75). 


Water-stage recorder just above Chamokane Ferry, \\ miles below Little Falls 
power plant of Washington Water Power Co., 4 miles below Chamokane Creek, and 
about 5 miles below Long Lake, in Lincoln County. 

Water is diverted above the station for irrigation. Flow is affected considerably by 
power regulation at Little Falls and Long Lake, and slightly by power regulation at 
Ninemile, Spokane, and Post Falls. Flow is also partly regulated at Coeur d’Alene 
Lake. 

Drainage area, 6,380 square miles (revised); measured by engineers of Washington 
Water Power Co. on maps of Spokane drainage basin, scale half an inch to the mile, 
compiled from best sources available.

Note.— During the year ending Sept. 30, 1919, information is not available for determining monthly 
storage regulation effected in Conconully and Salmon Creek reservoirs. Therefore correction for storage 
accumulation or release, as given in the preceding tables for the years ending Sept. 30,1912 to 1918, is not 
possible. During the year ending Sept. 30, 1919, storage decreased about 40 acre-feet in Salmon Lake 
reservoir, and increased about 50 acre-feet in Conconully reservoir. Hence the net storage during that 
year increased about 10 acre-feet.

CHELAN RIVER AT CHELAN (91). 

Staff gage at lower highway bridge at Chelan, 800 feet below dashboard dam at 
outlet of Lake Chelan, in Chelan County. 

Several irrigation ditches divert from tributaries a very small proportion of the 
run-off. The dam at the outlet controls lake level at low water in the interest of 
navigation. Monthly mean discharge has been corrected for natural and artificial 
storage in Lake Chelan. 

Drainage area, 950 square miles; measured on topographic and Forest Service maps.

Staff gage one-eighth mile below power plant of Wenatchee Valley Gas & Electric 
Co., three-fourths mile west of Entiat, and 1 mile above mouth of river, in Chelan 
County. 

There are several diversions above the station for irrigation. The Entiat Irrigation 
Co.’s high-line canal (capacity about 15 second-feet) carries water past the station- 
Monthly summaries show estimated diversion and depletion on account of irrigation. 
Flow is affected by changes in load at power plant. 

Drainage area, 419 square miles; measured on topographic maps.

Note.— Maximum discharge during period of record, 5,150 second-feet June 17,1916; minimum discharge, 
62 second-feet Nov. 13, 1916. Flow past gage in canal estimated from two discharge measurements and 
high-water mark in canal. Distribution by months made on basis of six-year record of Wenatchee Recla¬ 
mation District canal at Dryden. Depletion above gage based on careful studies of irrigation in Yakima 
basin. (See Water-Supply Paper 369, pp. 50-55.) Total depletion assumed to be 2.8 feet an acre. Basin 
is small and return flow probably reaches river in short time. Depletion is therefore distributed by months 
in same proportion as estimated diversions. Mean discharge for October, 1910, based on actual record 
Oct. 5-9 and hydrographic comparison with Wenatchee and Methow rivers.

Staff gage 1,500 feet below highway bridge at Plain, half a mile below Beaver Creek, 
and 14 miles north of Leavenworth, in Chelan County. 

The Wenatchee Park Land & Irrigation Co. has diverted a maximum of about 12 
second-feet from Chiwawa River since the irrigation season of 1914. Flow regulated 
by natural storage in Lake Wenatchee. 

Drainage area, 591 square miles; measured on topographic maps.

WENATCHEE RIVER AT CASHMERE AND DRYDEN (96). 

Staff gage prior to October 13,1909, at highway bridge in Cashmere, half a mile below 
Mission Creek, 8 miles above mouth; October 13, 1909, to September 30, 1911, at high 
way bridge half a mile above Mission Creek; thereafter at Wenatchee Valley Gas & 
Electric Co.’s power plant a quarter of a mile north of Dryden, 1 mile below intake of 
Wenatchee Reclamation District canal, and 4 miles above Cashmere, in Chelan 
County. 

There are many diversions for irrigation above the station. The Wenatchee Recla¬ 
mation District canal is the most important. Depletion caused by irrigation above the 
station is estimated and added to record of flow in river and canal to give probable 
natural run-off. Flow is regulated slightly at mill pond at Leavenworth. 

Drainage area, 1,280 square miles (revised), to October 12, 1909; 1,200 square miles 
thereafter; measured on topographic maps.

a Maximum and minimum determinations prior to 1911-12 refer to flow at river gaging station. During 
and after that year they refer to combined flow of river and canal. 

b Estimated monthly mean discharge of canal prior to June, 1911, used only to obtain natural run-off. 
Considerable error in estimate of discharge of canal makes small percentage error in total flow.

a The sum of the mean monthly discharges of the Tieton near Naches, Naches at Oak Flat, and Yakima 
at Cle Elum amounts to 723 second-feet for this month. On this basis the true natural flow at Union Gap 
must have been at least 800 second-feet. See Water-Supply Paper 369, footnote a, p. 49.

NACHES RIVER AT OAK FLAT, NEAR NILE (128). 

Water-stage recorder (PI. VIII, A) just above Oak Flat, three-fourths mile above 
intake of Selah Valley canal, 2 miles above Tieton River, and 8 miles southeast of 
Nile, in Yakima County. Staff or cantilever chain gages, read once or twice daily, 
in use prior to September 20, 1911. 

Numerous small irrigation diversions above station cause a depletion of less than 
5 per cent of natural flow. Flow partly controlled by regulation in Bumping 
reservoir; monthly discharge without storage, beginning November, 1910, determined 
from records of stage at reservoir. 

Drainage area, 640 square miles (revised); measured on topograhic maps.

Note. —Maximum discharge during period of record, 4,200 second-feet at 3.30 p. m. Nov. 23, 1909; mini¬ 
mum discharge, 127 second-feet, Jan. 12, 1910. Discharge estimated by comparison with records at other 
stations, November, 1908, to March, 1909, February and March, 1910, and February, 1911. Except for short 
intervals, results are based on gage readings taken from 2 to 7 days apart; discharge for periods during 
which gage heights are lacking estimated by comparison with records for Tieton River at headworks of 
Tieton canal. 

TIETON RIVER AT HEADWORKS OF TIETON CANAL NEAR NACHES (135). 

Water-stage recorder (PL. VII, B) about 1,000 feet below intake of Tieton canal, 15 
miles above mouth of river, and 16 miles southwest of Naches, in Yakima County. 
Staff gages, read once or twice daily, used prior to July 28, 1909. 






























































































264 HYDROMETRIC DATA IN WASHINGTON, 1878-1919. 

Tieton canal has diverted water above the gaging station since 1910; discharge in 
canal added to obtain natural discharge. Flow slightly controlled, to avoid diurnal 
fluctuation, by regulation in Clear Creek reservoir since 1915. 

Drainage area, 240 square miles (revised); measured on topographic maps.

Note.— Maximum discharge during period of record, 728 second-feet at 9 a. m. June 18, 1916; minimum 
discharge. 7 second-feet at noon Nov. 12, 1916; discharge may have been less during some winters when 
record was discontinued. 

Monthly means for April and May, 1910, were computed by subtracting the discharge at South Fork 
from that at “The Narrows’’ station. The mean for March is found bv making a similar estimate for 
the period Mar. 10 to 31. This estimate gives only approximate results for March as there was probably 
a considerable inflow from the intervening area, but the results for April and May are probably fair, as 
the inflow had largely ceased by that time. Monthly discharge August to December, 1911, and January to 
March, 1914, partly estimated by comparison with other gaging stations in the Ahtanum basin. 

Discharge for year ending Sept. 30, 1912, not previously published, on account of uncertain gage-height 
record. The results for that year should be used with caution.

WHITE SALMON RIVER NEAR UNDERWOOD (180). 

In 1912-13 at Conduit dam, 3 miles above mouth of river; beginning in 1915 just 
below Northwestern Electric Co.’s power plant, 2 miles above Underwood and mouth 
of river in Klickitat County. Reference point used at upper site; water-stage recorder 
at lower site. 

A considerable amount of water is diverted above the station for irrigation. At 
low and medium stages practically all the water is used through the wheels of the power 
plant. The pond above the dam covers about 80 acres and is drawn down 6 or 8 feet 
at times. Daily discharge has been corrected for pondage for practically all days 
when discharge was less than 1,000 second-feet.
